Generally I twist strands together, solder, fold back flat, slide heat shrink over each core and then heatshrink over the whole sheath. So the joint is fairly secure and loose connections are unlikely and it looks neat.

Is there any crimp device for joining cables that would mean less work? Something like a 6 way butt/splice or one that doesn't require insulation to be stripped (IDC)? Or is it just as handy to do it my way if I'm not going to be jointing regularly?

Hi: Look for closed end wire splices on eBay. Simple to install, just strip and twist then crimp on cap. That's it, job done.

There are Small Tell filled (Waterproof) IDC connectors available, originally made for Telecom work & need a special crimping tool to do the job properly. Some people don't agree with using them for stranded wires, but we used to be supplied with big boxes of them and to be honest I've never had any problems with them. Again available along with the tool, via eBay at quite good prices.

Have also seen a lot of jobs where the Red butt splice crimps have been used.

 

 

Hope that helps: Andy

No man this is worst solution 

 

They designed for telephone "solid" single core

 

Even house bashers wouldn't use them , gel crimps are worse than twist and tape , and twist and tape works

You must be an IT man.....

Al: I know what Gel crimps are for & no mate not IT, large national installer. Boxes of Gel crimps were what we had provided for repairing & extending alarm cables over several large sites where the cables had been vandalised and couldn't be replaced due to finished walls / floors & ceilings. Many of these were used, with as far as I know no adverse effects either in the short or long term.

Not my preferred way of doing it but they do the job.

You can't beat solder and heatshrink, both from function or aesthetics.

I wouldn't recommend butt splices at all just asking for trouble, if nationals use them or not that's up to them but your just asking for high res issues.

Never seen them used as butt splices on alarm cables. They strip & twist the conductors together, put the twisted joint into one end of the butt connector then crimp as well. 

Wasn't talking about the national using butt splices, that was the Gel IDC crimps.

No argument from me, my preferred way wherever possible.

Why would using a butt connector, be asking for high resistance issues ?.

9 times out of 10 they are not used correctly and the cable is not crimped firmly, most other connector types reduce the cross sectional contact area hence the resistance issues.

 

Soldering and heat shrink is where it's at...

Nothing is foolproof to a sufficiently talented fool.
